DP3S problem needs help!

[taotaollll]

Now he has a problem
1. It has been tuning.
2. Its buttons are not available up and down.
3. Press the ENTER key and the menu will scroll down.
4. Test chip pins (RC0 = 0V) (RC1 = 0V) (RC4 = 5V) (RC5 = 5V)
5. The 4 pull-up 10K resistors of the switch have been installed.
6. The chip's RC0 RC1 is not shorted to ground.

Good job! But your PCB is a old version. So, you can not use your buttons. You should use last version PCB

[taotaollll]

The button part circuit has been modified to the correct circuit

Did you modified it? If you had modified, which version schematic have you been use?

The chip button related circuit has been checked many times.
I suspect that there is a problem with the chip's program.
Because his RC0 and RC1 have no voltage.
Both chips are the same fault.

What is the sofware version?

[taotaollll]

two chips purchased last month and TE2012 one
version is full 5.7

Ok but your mistake about schematic. 3sV2 schematik is workin V6.0 sw and we are not selling this sw. You should use Job1 file for make your PCB

OK, then the buttons up and down are connected to the chip's RC6/TX and RC7/RX?

yes but don't forget pull up resistors.

[taotaollll]

The buttons are connected up and down to the RC6/TX and RC7/RX chips and will not work.

[Karadağ]

The buttons are connected up and down to the RC6/TX and RC7/RX chips and will not work.

Check the open diagram due to job1 file. When both of them will be same, device will work.

[taotaollll]

It is not working abnormally, but the display does not work when the chip RC7/RX is connected to the pull-up resistor.

OK, it's normal now, PBC has interference and needs to be re-layout. .
thank you very much.

thank you very much.

Ok, we awill wait your test videos

[taotaollll]

Ok, I will record the video when I test it after debugging.
Thanks again
